Did you ever see a sign or a billboard that used a lowercase L that looked like a capital I — especially when all of the other letters in context were capitalized? That’s happened maybe 3 times since college (which ended in 2000 for me) and nowhere near enough to make a blog out of it I would think — but apparently it happens more frequently than I reckoned! And here you go, take for instance LowercaseL.blogspot.com citing such syntaxial (?) atrocities. I had no idea.
